605 owner reviews, fewer than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other water filtration: replacement filters, under-sink and reverse osmosis systems, filter pitchers, water dispensers, coolers, faucet filters and softeners we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The Waterdrop WD-F22 arrives as a three-pack at $30.99, putting the per-unit cost at approximately $10.33. It carries NSF certification, which confirms independent third-party testing, though the specific NSF standard number is listed simply as 'NSF' without further breakdown in the available product data.
With dimensions of 2.2 x 6.5 x 8.7 inches and a weight of 1.7 lb, buyers have concrete sizing information to cross-reference against their refrigerator's filter housing specs. The three-pack format suits buyers on a six-month replacement cycle who want to stock a year and a half's worth of filters at once.
At 605 reviews and a 4.6-star rating, the WD-F22 has a moderate feedback base. It is smaller than Waterdrop's highest-volume models but is still consistent with the brand's track record. The 4.6-star score is solid and suggests the filter performs well for compatible refrigerators, though buyers should check compatibility carefully given the narrower model-specific footprint.
Pros
- NSF certified for third-party quality verification
- Three-pack provides roughly 18 months of replacements on a six-month schedule
- Physical dimensions published for fit verification
- Waterdrop brand with established customer support and broad catalog
- Per-unit cost of approximately $10.33 is reasonable for a certified three-pack
Cons
- 605 reviews is a modest base compared to higher-volume Waterdrop models

- No capacity figure in gallons is published
- At $30.99 for three, slightly more expensive per unit than Waterdrop's most affordable three-packs

Performance notes
The filter carries NSF certification for third-party evaluation. Without a specific NSF standard number confirmed in the product data, the scope of the certification cannot be precisely stated. The standard minimum expectation for NSF-certified refrigerator filters is reduction of chlorine taste and odor. No capacity data is listed. Dimensions are 2.2 x 6.5 x 8.7 inches and weight is 1.7 lb.
What buyers say
Rated 4.6 stars from 605 reviews, buyer sentiment is positive. The review count is smaller than Waterdrop's flagship filters but is sufficient to signal consistent performance. For model-specific filters with narrower compatibility, a 600-plus review count with a 4.6-star average is a reliable indicator that fit and taste performance hold up in real-world use.

Frequently asked questions
How do I confirm the WD-F22 fits my refrigerator before buying?
Check your refrigerator's owner manual or the sticker inside the filter compartment for the original filter part number. Compare that against the Waterdrop WD-F22 compatibility list. You can also measure the existing filter housing opening and compare it against the published 2.2 x 6.5 x 8.7-inch dimensions as a secondary check.
Why is the NSF standard number not listed in more detail?
Some aftermarket filter listings note NSF certification in general terms rather than specifying the exact standard. The most common applicable standard for refrigerator filters is NSF 42 for taste and odor reduction. If the exact standard matters for your needs, contact Waterdrop customer service directly to confirm which NSF standard the WD-F22 is certified under.
